Regenerated every touched file from origin/main applying only the B1 test deletions and the unused import and helper cleanup they leave behind, without running the formatter across untouched code. CI only checks ruff format under litellm/, so the earlier reflows of test files were pure diff noise for reviewers
Also drops the tests/local_testing/test_prompt_caching.py entry from the caching-local shard in test-unit.yml since that file is deleted

The repo rule is that a test must only fail when litellm code changes, never when a vendor updates a price, renames a field, or drops a model. These tests asserted shipped catalog entries directly, comparing lookup results to literals copied from model_prices_and_context_window.json or requiring named entries to exist or be absent, so every cost map sync could break them without any litellm code changing
Tests that exercise real litellm behavior with an injected local model_cost, invariants like backup parity, and assertions on non-lookup code paths are untouched

A temporary-only member update no longer clones the team default budget into the private row. The row stores just the temp pair and auth, spend admission and reservation add the active increase to the current shared default, so a later lowering of the default reaches members with an active grant

Custom auth callables that already capped an end user keep their cap; the key
default fills only unset limits. The proxy-wide default still reaches an
uncapped custom-auth token, and the missing-budget log strips line breaks

A service-account key can now carry end_user_budget_id in its metadata. When a request through that key names a customer that does not exist yet, the key's budget is applied to the new customer from the first request and wins over the proxy-wide max_end_user_budget_id. A customer with an explicitly assigned budget keeps it. The Admin UI exposes the setting on service-account key creation and key edit, and only proxy admins may set or clear it.

Adds temp_budget_increase and temp_budget_expiry to the team member edit form with pair validation,
seeds stored values into edit mode, sends both through /team/member_update, and adds cached-key auth
and reservation regression tests for active and expired increases

assert_never landed in typing in 3.11, so importing it from typing broke the
3.10 import smoke job and the py310 typing gate. Take it from typing_extensions
like the rest of the proxy does.
Also drop /team/update from test_neighbouring_team_routes_stay_closed. The route
is self-managed now, so the coarse gate admits the caller and update_team decides,
which the sibling test in the same file already asserts.

Team admins could never reach POST /team/update: the route gate answered
401 before the handler's team-admin branch ran. This moves /team/update
into the self-managed routes, resolves proxy admin, org admin or team
admin inside the handler, and filters team admins through a new
proxy-wide UI setting, team_admin_editable_team_fields. The setting is
an allow-list of team fields. Empty means team admins cannot edit team
settings and get a 403 pointing at the proxy admin, and changing a field
outside the list fails 403 naming that field. Only values that differ
from what is stored count, since the dashboard resends the whole form.
The registry of fields the setting accepts ships empty on purpose. Each
field lands in its own follow-up PR with its value diff and dashboard
wiring. The Admin UI gains a "Team admin editable fields" section under
Settings > UI and a toast on the team page while editing is disabled.

A budget bypass that ships off by default stays open for every deployment
that does not know to look for the flag, so `enforce_fallback_budget` now
defaults to true and `general_settings.enforce_fallback_budget: false` is
the opt-out for anyone who wants the old unguarded behaviour back.
BREAKING CHANGE: a paid fallback target is now refused for callers who are
over their key or user `max_budget`. Deployments relying on fallbacks to
keep serving over-budget callers must set enforce_fallback_budget: false.
Budget is enforced once during auth, against the requested model group.
`_is_model_cost_zero` waives every budget check for a zero-cost group, and the
router then picks a fallback target afterwards, inside `run_async_fallback`,
where nothing re-checks budget. A free model with a paid fallback therefore
bills with no budget gate at all.
Add `fallback_budget_check`, the budget sibling of the existing
`fallback_access_check`: a predicate awaited per fallback target that skips
targets the caller cannot pay for. The primary attempt is untouched, so a
zero-cost model is never blocked by budget and only the paid fallback is
refused.
Counter reads pass `max_budget` so `get_current_spend` verifies against
authoritative recorded spend, matching the auth-time key and user checks; a
counter restored from an older snapshot reads as a hit rather than a clean
miss, so without it a stale-low value would keep admitting paid fallbacks.
A zero-cost fallback target is always allowed, and a team key does not inherit
the key owner's personal budget unless `apply_user_budget_to_team_keys` is set,
matching `_PROXY_MaxBudgetLimiter`.
Scope is key and user budgets. Team, team-member, end-user, org, global and
per-model budgets are not covered yet: those auth-path functions enforce rather
than report, so reusing them would fire threshold alerts and take spend
reservations for a target that is then skipped. Two limitations of that scope
are documented in the module docstring: the check reads the spend counter
rather than reserving against it, so concurrent fallbacks can cross a cap
together; and a request reaching the router without
`metadata["user_api_key_auth"]` is not restricted. Both are shared with
`fallback_model_access.py`.
Opt-in via `general_settings.enforce_fallback_budget`.

Drop the model_access_denied_message setting, its {model} template, the DB
override entry and the Admin UI field. Model access denials now always return
the fixed client message while the allowlist diagnostic is logged at the final
HTTP, realtime and MCP boundaries

A team can now carry a per-model budget map that every key on the team
inherits. A key's own model_max_budget entry for the same model takes
precedence, so it is gated on and billed to the key alone.
Backend: NewTeamRequest/UpdateTeamRequest accept model_max_budget (validated
like the key-level field, enterprise gated); the value is hydrated onto
UserAPIKeyAuth via the token view, TeamGrants and the carried budget state;
_check_team_model_budget enforces it in the centralized common checks; the
limiter meters spend under team_model_spend:<team>:<model>:<duration> and
skips the team counter when the key overrides; /team/update lets only a
proxy admin raise, re-window or drop a cap; /team/info exposes usage.
The Anthropic context-management compaction summary subrequest runs the
same team gate. Both fallback token-view SQL definitions project the column.
UI: team create and edit forms reuse the key-level ModelMaxBudgetEditor,
premium gated, sending {} to clear and omitting unchanged fields.
A key entry overrides the team cap only when it spend-gates the model
(non-negative max_budget); a row that only carries tpm/rpm limits or a
negative cap leaves the team cap in force.

Post-auth denials from can_key_call_resolved_model (per-request alias
rewrite, MCP sampling, realtime) never reach the auth exception handler,
so the internal allowlist reason was dropped when
model_access_denied_message was set. Log it once from the ProxyException
response handler and the realtime rejection path instead, and convert
JWT ModelAccessDeniedHTTPException into the specialized ProxyException so
the same boundary covers it

Move the WARNING that carries the internal denial detail out of the message formatter and into the auth exception handler. The denial exceptions now carry internal_message so access-group probes and fallback paths that catch and recover from the denial no longer log a false denial for an allowed request

Match the pass-through skip to what FastAPI actually dispatched (the user-defined
endpoint marker or a provider handler's {endpoint:path} param) instead of the
mapped route prefixes, which also cover native routes such as /openai/v1/responses
and /cursor/chat/completions. Wrap the added test lines to the 120-column limit.
